The R1 just came out so not many people have it yet. The first batch was shipped out today for everyone that pre-ordered. You will see reviews/impressions coming up in near future.

SoundMagic e30 is amazing. The best IEM you can get for under $50 for now. It has natural sound with amazing tonal quality. Has a hint of warmness and a touch of added bass. It also has a good soundstage, about 75% of a Sennheiser IE8 imo.

I think R1 could be simliar to e30, but better soundstage and bass. I will let you know as I ordered one, and I already have e30 on me.
